Short and compact like any CQB gun should be. Threw a tight bore in the first day so I can't attest to the accuracy out of the box, however mine is able to hit a head sized target from 150 feet, first shot. Definitely did not expect that when purchasing. Blow back is great, feels like a .22 with a great sounding bolt. Cool down is mitigated through the large gas capacity, allowing roughly 60 shots per full charge. Since it is a gas gun, it is completely dependent on the weather and would not be advisable in cold conditions. That being said, I have used it in sub-freezing temperatures and as long as the mags are kept warm somehow, it doesn't suffer too badly. The body itself is extremely sturdy and feels like the real HK polymer. It breaks down very nicely and it is possible to access any part of the gun without tools, minus the barrel nut. It is a CCW thread so aftermarket flash hiders will fit, but if you are looking to get a suppressor, I would recommend the K version as it will hit the hand guard of the C and not fit.
Can fire full auto through a whole mag no problem.
Crisp trigger pull
Quality forward rails
Pretty much ambi with only the side folding stock being in the way of a lefty.
CHEAP FOR A GAS RIFLE
Ugly stock flash hider is glued on with industrial adhesive, hard to get off.
No flip up sights (can buy as an upgrade)
Low cap, good or bad.
